A QR code, or Quick Response code, works by encoding information in a two-dimensional barcode that can be easily scanned by a smartphone or other digital device. When a QR code is scanned, the encoded information is quickly read and interpreted by the scanning device, which can then display the encoded information, such as a website URL, text, or contact information. This allows for quick and easy access to the encoded information without the need for manual input. QR codes are commonly used for marketing, ticketing, product tracking, and other applications where quick access to digital information is needed. **
